Chapter 1 Introduction 5
■ Graceful shutdown. Use a non-conducting pointed object, such as a stylus, to
press and release the Power button on the front panel. This causes Advanced
Configuration and Power Interface (ACPI) enabled operating systems to perform
an orderly shutdown of the operating system. Servers not running ACPI-enabled
operating systems will shut down to standby power mode immediately.
■ Emergency shutdown. Press and hold the Power button for four seconds to force
main power off and enter standby power mode.
When main power is off, the Power/OK LED on the front panel begins flashing,
indicating that the server is in standby power mode.
Note – To power off the server completely, you must remove it from the chassis, or
disconnect the AC power cords from the back panel of the chassis.
Note – Pressing the Power button for four seconds or more always causes the
subsystems in the server module (except for the service processor) to be powered off,
even if the server module is already in the powered-off state.
If the server module is already in the powered-off state when the Power button is
pressed for four seconds or more, power is briefly applied to the system, then it is
turned off again.
About Diskless Servers
The Sun Blade X6450 is a diskless server. This means that you cannot install the
operating system on a local disk because it does not have one.
Instead, you have other choices. These include:
■ Installing the operating system on the compact flash, which shares characteristics
with a hard drive, and which can support some operating systems. This option is
described in “Compact Flash Drive” on page 6.
■ Installing the operating system on the SSD, or Solid State Disk device. See “Solid
State Disk Drive (SSD)” on page 7.
■ Configure diskless network boot, which boots the server module from a boot
image on another server. See the Sun Blade X6450 Server Module Operating
System Installation Guide or your operating system documentation for more
information.
